Not as far as I can see. This does appear to be unique to an interaction with BFS and the new block plugging code. Although test9 does so far seem to fix all the remaining problems. There is a small possibility this could happen on mainline as well, but is much harder to hit due to design differences.

So far so good here with test9. Since all of the previous test patches that worked well for others were still fucked off for me, I imagine if there's any remaining breakage here I'll run into it pretty soon. ;)
